Project Overview
This research focused on investigating bacterial biofilm adhesion on various material surfaces, aiming to understand the fundamental mechanisms of a prototype for biofilm adhesion tester at the nanoscale (TLR 1-3). The project utilized Advanced Electron Scanning Techniques (SEM), Atomic Force Microscopy (AFM), and in-house micro-mechanical testers to analyze bacterial attachment on different surfaces under controlled conditions.
The study was funded with €100K from Science Foundation Ireland (SFI) and conducted in collaboration with the University of Zagreb. It resulted in several journal publications and conference presentations, establishing a strong scientific foundation for understanding bacterial adhesion behavior. Additionally, preliminary industry and market research explored applications in water treatment technologies, particularly in nanofiltration (NF) membranes as a potential solution for biofilm-related fouling issues.
1. Business Opportunity
Market Need & Pain Points
Bacterial biofilms are a critical challenge across industrial, medical, and environmental applications, contributing to contamination, reduced system efficiency, and increased maintenance costs. Traditional approaches to biofilm control rely heavily on chemical cleaning, antibiotics, or material coatings, but these solutions are often ineffective in the long term due to resistance development and high operational costs.
One of the key gaps in current biofilm research is the lack of precise, quantitative adhesion measurement techniques. Without a clear understanding of how bacterial adhesion varies across different material surfaces, industries struggle to design optimized antifouling surfaces. This research aimed to bridge that gap by quantifying bacterial adhesion forces, providing crucial data for developing more effective biofilm-resistant materials.
Target Industry & Market Size
The global water filtration market was valued at $45 billion in 2013, with rapid growth due to increasing demand for clean water solutions across municipal, industrial, and healthcare sectors. The membrane filtration market, including nanofiltration (NF) and ultrafiltration (UF) membranes, was expanding at a CAGR of 8.5%, driven by the need for biofilm-resistant filtration solutions.
Key potential adopters of this research included membrane manufacturers, water treatment companies, and biotech firms developing antifouling materials. The insights generated through this study provided a scientific basis for further innovations in biofilm-resistant surfaces and coatings, opening opportunities for collaborations with the water purification and biopharmaceutical industries.
2. Technology & Competitive Advantage
Innovation Overview
The research operated at Technology Readiness Level (TRL) 1-3, focusing on fundamental and applied scientific investigation of bacterial adhesion. Using high-resolution microscopy (SEM) and nanomechanical testing (AFM), the project provided a quantitative understanding of bacterial adhesion forces under different conditions. Experiments were conducted on various engineered surfaces, including glass, polymers, and composite materials, to assess how surface properties such as roughness, chemistry, and hydrophobicity influence bacterial attachment. The findings established a scientific framework for predicting biofilm adhesion, which is critical for designing antifouling coatings and surfaces.
Key Differentiators
Existing biofilm control strategies rely on reactive approaches such as biocide treatment or mechanical cleaning, which can be costly and environmentally harmful. This study introduced a preventative approach by providing quantifiable adhesion data, enabling the rational design of biofilm-resistant materials. The project’s use of Atomic Force Microscopy (AFM) for bacterial adhesion quantification provided a level of precision previously unavailable in biofilm studies. Unlike traditional staining and imaging methods, this technique allowed for real-time force measurements, capturing the exact interactions between bacterial cells and material surfaces at the nanoscale.
Additionally, the development of in-house micro-mechanical testers allowed for customized adhesion testing, making this approach adaptable to various industries beyond water treatment, including medical implants, food processing equipment, and bioreactors where biofilm control is essential.
3. S2B Strategy & Industry Engagement

While primarily an academic research initiative, this project integrated preliminary industry and market research to identify real-world applications for biofilm adhesion studies. The findings indicated that water treatment technologies, particularly NF membranes, could benefit from biofilm-resistant surface designs.
The research was conducted in collaboration with the University of Zagreb, leveraging cross-disciplinary expertise in microbiology, materials science, and nanotechnology. This collaboration strengthened the project’s scientific validation, ensuring that the findings were rigorously tested and reproducible across multiple experimental conditions.
Educational Marketing & Market Positioning
To establish credibility in both scientific and industrial communities, the research team actively participated in conferences, academic workshops, and industry events. Findings were published in high-impact journals, contributing to the broader knowledge base on biofilm adhesion and antifouling materials.
Additionally, preliminary discussions with water filtration and material science companies were initiated to explore potential applications.
